Tonight at KJ West, opera wasn’t merely played, it materialised.

Through the breathtaking combination of Wilson Audio Alexia V and the extraordinary dCS Varèse, every aria arrived with the scale, emotion and intimacy of a front-row seat at the world’s finest opera house. Breath, texture, stage depth and orchestral weight unfolded effortlessly, dissolving the line between reproduction and performance.

Moments like these remind us that great hi-fi is not about hearing more music. It’s about being there.

Fresh on demo tonight: the all-new Momentum Z mono amplifiers and preamplifier.

Paired with the iconic Wilson Audio WATT/Puppy, the result is simply extraordinary. Effortless power, absolute control, lightning-fast agility, and a level of musical engagement that’s impossible to ignore.

Sonically breathtaking. Visually stunning.

Come and hear what happens when world-class engineering meets world-class loudspeakers.

Tonight at KJ West One

We’re thrilled to host Grant Samuelsen of Shunyata Research for an evening dedicated to the science and sound of clean power. 20+ years installing Shunyata systems in the world’s top recording studios (including Rick Rubin’s Shangri-La) and even in hospital cardiac labs - tonight he’s bringing that expertise to Marylebone.

Come hear it for yourself: our reference system running on Shunyata’s brand-new X range - Everest-X, Omega-X, Sigma-X, Alpha-X and the Altaira-X grounding hub.
